TURPENTlNE-STILL.

SPECIFICATION forming part of Letters Patent No. 785,469, dated March21, 1905.

Application filed August 11, 1904. Serial No. 220,310.

which the distillation of turpentineand other products from wood may bemore efiiciently and economically eflected than has been heretoforeattained.

With this object in view the invention consists in the novelconstruction and combinations of parts, which will be hereinafter fullydescribed and claimed.

1n the drawings, Figure 1 is a plan view of the improved apparatus. Fig.2 is a vertical section, as on the line 2 2 of Fig. 1, enlarged.

Fig. 3 is a similar section as on the line 3 3 of Fig. 1. Fig. 4 is alongitudinal vertical section of a modified form of the apparatus. Fig.5 is a similar view of another modified form of the apparatus. Fig. 6 isa transverse vertical section of the form shown in Fig. 5.

1 designates a receptacle or steam-drum, and 1 a pipe leading theretofrom any suitable source of steam-supp] y. The pipeopens into acentrally-arranged chamber 5, which extends into the drum 1 from therearward end thereof. The inner vertical wallof the chamber 5 isprovided with a series of perforations 6, and the circumferential wall 7of the chamber 5 is made tapering, as shown, for a purpose hereinafterexplained. The forward end of the drum is provided with a hinged door 8,by means of which access may be readily had to the interior of the drum.A suitable catch 9 and bolts 9 are provided to hold the door in placewhen closed, and interposed between the door 8 and the end of the drum 1is a gasket 10 to insure a steamtight joint.

Arranged within the lower part of the drum 1 is a trackway 11, which isadapted to receive a cylindrical charging-shell 12 in the form of atruck provided with carryingwheels 13, which support the shell upon thetrackway 11. The shell 12 is adapted to receive the pieces or chips ofpine or other wood from which the turpentineand other products are tobe'distilled. The ends of the charging-shell 12 are closed by removableheads 14:, which are provided with perforations 15 and flanges 16, asshown. The flanges 16 are fitted to the interior of the shell 12 andwhen placed therein and given aslight turn are held in place bybayonet-joints 17. By referring to Fig. 2 it will be seen that therearward end of the charging-shell extends slightly beyond its head 14and fits snugly around the tapering wall 7 of the chamber 5, therebyproviding a practically steam-tight joint.

Leading from the forward end of the drum 1 is a pipe 18, whichterminates in a condenser 19, which may be of any well-knownconstruction. The pipes 4 and 18 are provided with controlling-valves 20and 21, respectively, and the drum 1 is provided with a suitablepressure-gage 22 and a safetyvalve 23.

From the foregoing it will be seen that when the valves 20 and 21 areopen the steam passes from the pipe 4 into the chamber 5, thenthroughthe perforations 6 and into and through the charging-shell 12,and then out throughthe pipe 21 and condenser 19, the union between therearward end of the charging-shell 12 and the tapering wall 7 of thechamber 5 preventing the passage of the steam into the drum 1 withoutfirst passing through the charging-shell 12 and the wood containedtherein.

Terminating slightly in advance of the door 8 and in line with thetrackway 11 is a trackway 24:, which leads to a source of wood-supplyand which is provided with a branch trackway 25, leading to a point ofdischarge for the used wood. The end of the trackway 24 adjacent to thedoor 8 is provided with a hinged section 26, which when raised permitsthe door 8 to be opened and closed and which ber of the charging-trucks12 to the end that while the contents of one truck are being subjectedto steam within the drum 1 other trucks may be run upon the trackway tothe discharge-station and to the source of woodsupply for the purpose ofdischarging the used wood and refilling the truck with fresh wood.

The operation of the apparatus may be briefly described as follows:Assuming that the door 8 is closed and that a truck 12 charged withfresh wood is within the drums 1, the valves 20 and 21 are opened andthe steam rushes through the wood contained in the truck 12 and outthrough the pipe 18 to the condenser 19. The action of the steam uponthe wood vaporizes the turpentine and other products contained therein,which pass with the steam to the condenser 19, where they are recoveredin the usual manner. During the process just described anothercharging-truck 12 is run upon the trackway to the source of wood-supply.One of the end heads 14: is then removed and a charge of fresh wood isintroduced to the truck, the removed end head is replaced, and the truckis run upon the trackway to a position near the door 8 of the drum 1.After the turpentine and other products are distilled from the contentsof one truck within the drum'l the valves 20 and 21 are closed, the door8 is opened, the section of trackway 26 is lowered, and the truck withinthe drum 1 is run upon the trackway to the point of discharge.Immediately following the removal of the truck from the drum the truckcontaining the charge of fresh wood is run into the drum until its endfits snugly around the tapering wall of the chamber 5. The section oftrackway 26 is then raised, the door 8 is tightly closed, the valves 20and 21 are opened, and the process of distillation is carried on aspreviously explained. Thus it will be seen that by the construction andoperation hereinbefore described very little time and heat will be lostin removing a truck containing used wood from the drum 1 and replacingit with a truck containing fresh wood.

naled in the drum 1, in which event the trackway 11 would be dispensedwith and also the wheels 13, carried by the charging shell. Thesefigures also show the rearward end head of the drum 1 provided with aninwardly-extending annular flange, the inner face 7 of which is madetapering, as shown, to receive the end of the charging-shell 12, andthus provide a practically steam-tight joint.

While I have herein shownand described my invention in a desirable andpracticable form, yetI do not limit myself to this particularconstruction,as the same may be modified without departing from theinvention.

I claim-- 1. In a turpentine-still, the combination of a steam-drum, acharging-shell adapted to be placed within the drum and comprising animperforate body portion having end heads provided with openingstherein, and means for introducing steam to said shell through theopenings in one of its end heads whereby the steam is caused to passentirely through the shell before entering the drum.

2. In a turpentine-still, the combination of a steam-drum provided onits interior with a hollow tapering portion, acharging-shell havingopenings in the ends thereof and adapted to be placed within the drum toopen into and fit said tapering portion, and means for introducing steamto said drum within the tapering portion, whereby steam is caused topass through the shell before entering the drum.

3. In a turpentine-still, the combination of a steam-d rum provided withan opening therein and on its interior with a hollow tapering portion, adoor to close said opening, a charging-shell provided with supporting-wheels and having openings therein and adapted to be moved intoand out of said drum, and means for introducing steam to said drumwithin said tapering portion, whereby steam is caused to pass throughthe shell before entering the drum.

4. In a turpentine-still, the combination of a steam-d rum provided withan opening therein and on its interior with a hollow tapering portion, adoor to close said opening, a trackway within said drum, acharging-shell provided with openings therein and supportingwheelsfitted to said trackway and adapted to be moved into and out of saiddrums, and means for introducing steam to said drum within said taperingportion, whereby steam is caused to pass through the shell beforeentering the drum.

5. In a turpentine-still, the combination of a drum or receptacle havingan opening there in, a door to close said opening, a chargingshellprovided with supportingwheels and adapted to be moved into and out ofsaid drum, said shell comprising an imperforate body portion having endheads provided with openings therein, and means for introducing steam bemoved into and out of said drum and said trackWay being arranged todirect said shell to engage and open into said tapering portion, andmeans for introducing steam Within said tapering portion, whereby steamis caused to pass through the shell before entering the drum.

In testimony whereof I alfix my signature in presence of tWo Witnesses.
